An X-ray database, tools and procedures for the study of speech production

International audience This paper presents an X-ray database and processing tools that have been respectively elaborated and developed within a research project on speech production (DOCVACIM). The X-ray data deal with various phonetic issues in different languages spoken in Europe, in Africa, in Asia and in Latin America. The goal of the project, apart from looking into issues related to coarticulation, inversion and evaluation of physical models, is to make available to the speech scientific community: 1) a set of multilingual and multimedia data on speech production containing cine-radiographic images of the vocal tract, acoustic signals, tracings and contours of the vocal tract, all synchronized and accessible within a processing platform; 2) adapted tools and software that allow extracting articulatory information from these data, in relation with prior phonological labeling. The focus in this article is on the adapted tools and software which have been developed within the project.
